Let’s see how we can re-scan the SAN/FC luns on solaris 10/11 hosts.
To scan new FC luns, Just execute the below commands.

Scanning FC/SAN LUNS

1 cfgadm -al To scan FC luns
2 devfsadm -c disk To make sure all the device files are created
3 tail /var/adm/messages To see the new LUN’s information
4 echo |format To get the new LUN’s information
5 ls -lrt /dev/rdsk |grep s2|tail To get the new LUN’s information

“luxadm probe” also used to scan FC luns but i am happy to use cfgadm.
If you still not able to see the new LUNS/DISK ,then you can try to reset the HBA as last option if you have multipath enabled. (Do not try in critical servers unless you have confident on multipathing)

3. Verify the controller status using “cfgadm -al”.Make sure disks didn;t loose any SAN paths after the HBA reset. If everything seems to be okay ,then isssue the forcelip to the another controller.
If still you are not able to see the new FC/SAN LUNS ,then reboot the server and try. Once you see the new lun, make sure that multiple FC paths are enabled to that. Minimum two FC paths required for SAN disks.
” luxadm display /dev/rdsk/c1txxxxxxd0s2″ – To verify the FC lun details and multipathing.
